Question: proxy-wasm-go is thread safe or not?

[dozer47528]

Hi tetratelabs team, I am learning wasm-go from this example.

But I am worried about these two lines, which may change the slice at the same time.

https://github.com/tetratelabs/proxy-wasm-go-sdk/blob/main/examples/postpone_requests/main.go#L62

https://github.com/tetratelabs/proxy-wasm-go-sdk/blob/main/examples/postpone_requests/main.go#L89

For normal golang code, I need to use sync.Mutex.

It is safe in wasm-go? Why?

Proxy-Wasm in general is single threaded, not Go specific.
